"Chrome has been progressing rapidly through versions, and Google has communicated its intent to continue rapid development and short release cycles. As a result, we've modified our strategy for Chrome to advise testing on the latest [generally available] release of Chrome as soon as it is issued, with prior versions moving to X-grade as soon as they are superseded."

Now that Google Chrome has a new major release every six weeks, you won't see too many new features. Chrome 7 focuses on "hundreds of bug fixes", while Chrome 8 enables the internal PDF viewer. Chrome's releases aren't exciting because the browser is constantly improving and you don't have to wait one year or more to see the new features.
